As LaGuerta gets into her car, she sees Mrs. Tucci at her son's side outside the ambulance, and I can't really gauge her reaction. I'm actually a bit more concerned about why that dude isn't being rushed to the hospital.
Dexter's back in the car, VO-ing, "Everyone hides who they are, at least some of the time." As we see LaGuerta lighting a candle in church: "Sometimes you bury that part of yourself so deeply that you have to be reminded it's there at all." As we watch MacNamara celebrating his Guerrero victory with Doakes looking on, doing paperwork: "Sometimes you just want to forget who you are, altogether."
At the DexPad 2000, Dexter is at his air conditioner, pulling the face off and grabbing his blood slides, while VO-ing, "And what about me? Maybe I'll never be the human Harry wanted me to be." Now, looking at the picture of himself from earlier that evening: "But I couldn't kill Tony Tucci. That's not me, either. My new friend thought I wouldn't be able to resist the kill he left for me, but I did." As he lights the picture on fire: "I'm not the monster he wants me to be." Interesting, Dex. Maybe you're not totally the monster you fancy yourself, either. "So, I'm neither man nor beast. I'm something new entirely. My own set of rules. I'm Dexter." He blows out the burning picture, the only evidence of his being at the crime scene before leaving Deb her "tip," and I imagine it must smell really gross. As he does so, we go to black, and we're all left wondering why he felt the need to get his slides out. He didn't even kill anybody this episode, which kind of makes me sad, but also makes me feel like he has to kill someone next time!
